SWITCH.

Application filed April 18, 1925." Serial No. 24,182.

This invention relates to a switch and has for its primary object the construction of a switch in which parts work in a manner to assure clean electrical contacts at all times.

An obj ect of the invention is the construction of a switch that may be operated to the reciprocatory action of a single push button.

A feature of my invention is the simple novel manner of connecting and associating the parts so that the contact plate may have two movements and be accurately held in any position.

IVith these and other objects in view, the invention will be better understood from the following description taken in connection with the accompanying drawings, in which:

Fig. l is a side elevation of the switch.

Fig. 2 is a top plan with a part of the cover removed.

Fig. 3 is a vertical sectional view.

Fig. 4 is a detail view of the contact plate.

Fig. 5 is an enlarged side elevation with parts removed.

Again referring to the drawing illustrating one of-the many features of my invention, the numeral l designates a casing or base in which is mounted a rod 2. This rod 2 has rotatably mounted thereon, and also slidably mounted, a contact plate 3 provided with an extension 4 for movement into and out of engagement with the stationary contacts 5 and 6 carried by the casing. This plate is provided with cam shaped depressions 7 operatively associated with lthe cam elements 8 carried by the casing. Thus it will be seen that in the rotary movement of the plate the same will be given rectilinear sliding movement on the rod 2.

For giving rotary action to the contact plate I provide a ratchet device 9 comprising the usual two elements 10 and l1, one connected to the plate and the other to an arm 12 rotatably mounted on the rod and arranged in the path of movement ofthe plunger 13 that terminates in a push bu t ton 14. A single spring 15 is coiled around the rod 2 to yieldably hold the ratchet elebutton 14. In the sliding of the plunger the arm 12 is thrown in an arc of the circle and through the ratchet connection the plate is turned. Due to the cam action between the elements and the plate, the plate is moved vertically and then snapped into a position either in engagement or out of engagement with the contacts 5. Upon the release of the plunger the spring acts to return the plunger to a normal position and besides return one of the elements of the contact device to position to give further movement to the plate.

Having thus described my invention, what I claim is:

In combination, a casing, a rod carried by the casing, a contact plate rotatably and sli-dably associated with the rod and having depressed portions defining cam shaped elements, stationary contact elements carried by the casing, an arm defined by the plate and adapted alternately for engagement with the stationary contact elements, a ratchet defined by sectional parts, one of the sectional parts being connected to the plate, the other of the sectional parts being rotatably associated with the rod, and a plunger carried by the casing, said plunger having an end portion arranged in theipath of the arm and adapted for operative kengagement therewith, substantially as described.

In testimony whereof I'afix my signature.
